Basically you can build using a debian or ubuntu but there are some 
details that differentiate the build result (eg when building under 
Ubuntu, Plymouth does not work as expected) The best result is achieved 
when you use the following base system:
- Xubuntu 32bit base with SAME kernel version as the Xubuntu iso (if you 
want updates use apt-get upgrade instead of apt-get
dist-upgrade)
- User account to run the build script should be "user" since this 
account will be used during chroot to run the scripts. We do that to 
keep backward compatible scripts and not be forced to rewrite them all 
from scratch.

About bootstrap, yes you only need it once and then you can svn up and 
rerun the build as many times as you like.

For building the official disk I use a base VM and change it only when 
we change kernel.

We have a build_chroot_debug.sh to help you enable and disable packages 
and make smaller tests, rather than building the whole iso each time. 
Just make sure to enable the packages you need as dependencies. This 
script will be copied in the chroot environment and be used. Caution: 
the scripts are not moved into chroot, they are svn checkedout from 
within the chroot, so any change you do on a project script should be 
copied manually by you or committed in order to be tested.

This folder will be deleted and recreated on next run.
I wanted to implement this feature (keeping the installation files to be 
reused) but I did not have the time so far...
